It’s T-minus six weeks until “Avengers: Infinity War” opens and Marvel has unveiled the final trailer to tide you over ‘til then. This one offers a much closer look at Josh Brolin’s supervillain Thanos, who, if you didn’t know any better, just sounds like he wants to collect a bunch of rocks. Alas, those rocks are the universe-destroying Infinity Stones.

“The entire time I knew him, he only ever had one goal: to wipe out half the universe,” Gamora (Zoe Saldana) says. “If he gets all the Infinity Stones, he can do it with the snap of his fingers.”

All our favorite Marvel Cinematic Universe heroes, from the OGs like Iron Man (Robert Downey Jr.) and Captain America (Chris Evans) to newbies like Spider-Man (Tom Holland) and current box office king Black Panther (Chadwick Boseman), assemble to take down Thanos. Though they’re not all exactly on the same page yet.

“Let’s talk about this plan of yours,” Star Lord (Chris Pratt) tells Iron Man. “I think it’s good — except it sucks. So let me do the plan, and that way, it might be really good.”

With this film being the end of Phase I of the MCU, you know that not all of them will probably make it out alive. That final shot of Thanos’ massive fist trying to knock out Cap’s pristine set of teeth is rather ominous.
